EXCLUSIVE: “I kept saying to myself, what has happened in America?” recalls a pained Rep. John Lewis of the 1968 assassination of the New York Senator in the new trailer above for Netflix’s Bobby Kennedy For President.

Nearly 50 years after RFK was fatally shot at LA’s Ambassador Hotel on June 5, 1968, the Dawn Porter directed four-part docuseries debuts on the streaming service on April 27. That launch of the interview filled and archival footage rich project actually follows a premiere of Bobby Kennedy For President at the Tribeca Film Festival two days beforehand, on April 25 in NYC.

As the first look above makes clear, the RadicalMedia, Trilogy Films and LooksFilms produced docuseries delves into the changes in the former Attorney General outlook and political beliefs over the 1960s and especially after the death of John F. Kennedy in late 1963. Focusing on the younger Kennedy’s 83-day race for the White House in that tumultuous year of 1968, Bobby Kennedy For President also casts its net towards the present. The docuseries examines the impact on American history that RFK’s Presidency could have had and that toll that his sudden death certainly did have.

“It was a thrill to explore Bobby Kennedy’s life through the beautiful archive film we uncovered,” Porter told Deadline of the project on the deeply mourning sibling of the 35th President of the United States. “Bobby Kennedy remains one of the most important and influential figures in American political history, but his story is not as familiar to the newest generation of leaders,” the Gideon’s Army helmer added of the relevance she believes RFK’s tale and life have to a divided America of 2018 under President Donald Trump.

“He challenged those around him in powerful positions to ask, ‘ How can we do better’ and he listened to young activists like Rep. John Lewis and Marian Wright Edelman, leaders whose commitment to equality move the nation forward on a path towards social justice today,” Porter says of Kennedy, who launched his Presidential bid on March 16, 1968. “With all the political upheaval America is living through, we all felt that there was no better time to study Bobby Kennedy’s life and legacy. I’m really honored that Netflix entrusted me with a story of this scale.”
